New Mystery Box Finds

So I just updated my Springfield #2, And I got the dialogue between Mr Burns and Smithers about the "New Mystery Box" and then they gave me a FREE Mystery Box.. But when I updated my Springfield #1 about 12 hours ago, I did see that there was the NEW Mystery Box in the shop (For 6 Donuts), BUT I had no dialogue between Mr Burns and Smithers, and was not offered a FREE Mystery Box.. Was everyone supposed to be offered a FREE Mystery Box?? Just confused, but ehh it's all good! Oops.. I guess I should have read A FEWWW more posts before I posted.. Mr Burns is busy waving at people to come join his Eyes Wide Shut party at the moment, So I see the dialogue can't be triggered yet!
